Having the zone 2 inch level installed this morning at 10:30. Still undecided on perfect tire size. Won't be off road but want a better stance with no rub problems. So many options here on this thread. 2 inch level up front. Stock block in back. Using my stock 20's I need a tire choice that's gonnagive me more rubber without sticking out the sides. Thoughts?

EDIT: zone 2 inch with G2 285/55/20.

 

No such thing as "perfect size". Just what you like...and sometimes even that changes. Pretty quickly sometimes. If you're not going off-road, stick with a mild A/T type tread or even a street tread. You'll be happier in the long run. They are quieter, ride nice, and generally have less rolling resistance.

Shocks like the Kings and Fox may have longer extension than stock. Frankly, I didn't measure my Kings against the OEM Ranchos for full extended free length when they were out of the truck. I installed the Cognito UCAs because I knew that GMT900 trucks needed them with the King shocks and these trucks use the same suspension.

 

Anyone using spacers like the RC kit, might benefit from an aftermarket UCA with the adjusted ball joint angle. I just don't sign up to the idea a dry Teflon socket with a steel ball, exposed to the dirt and elements, is going to last very long. I hear they also develop a squeak.

 

For anyone contemplating an aftermarket UCA, forget about the cheapest one on the market @ $250, the Rough Country UCA. It is designed poorly and interferes with the frame fittings. No amount of grinding on the frame as they recommend, allows for complete factory camber/caster adjustment range.

I completely disagree, I just installed the RCA UCAs and the fit was perfect, no issues with alignment and at a minimum address some of the steep angle and have greaseable/replaceable upper BJs...not bad for the price...and I guess my theory on your issue is these UCAs are specifically spec'd for at least 3.5" of lift. Because you are running less it's not RCX's fault that they didn't spec out for a setup outside their designed use...not being an RCX cheerleader but just want to communicate the facts.

Well, it really isn't about whether you disagree or not. The fact is it doesn't make them fit my truck.

 

You can see in the picture that the full camber/caster adjustment isn't possible with the RC UCA, even after I ground over 1/2" off my frame, down to the point of the camber/caster indexing cam pin. Regardless of the leveling, the UCA has to travel the same path unimpeded when the suspension compresses. RC just didn't put the small dogleg in the beam like the factory and every other UCA maker selling them for this truck.

 

The facts are that the control arms were represented to me by a RC sales staffer to work with King shocks at 2" level and that full factory range of adjustment is not achievable with the RC UCA.

 

You might want to check your UCAs for rubbing on the frame in this area during full suspension travel.

Yeah I checked my clearance because your pics scared me, to the point I almost didn't order the UCAs, but mine don't have any issues like yours did.

Negative they make a +1,+14, and +20 in the 20x9

I believe it's +14 or 18. Fuel only makes the 20x9 in one offset

never_rested_24-7 is right. They make those sizes and the only difference between the 3 is the amount of backspacing. The lip size is all the same though. About 1.83" or some odd number like that.

Sorry, I shouldn't have jumped down your throat. I just don't like aftermarket parts that don't fit right. One of my pet peeves.

 

In this pic, you can see RC took a direct line to the bushing on that leg of the UCA. The tube cuts across over to the bushing and intersects it at an angle. (the tubes on the outside of the pic)

On the Cognito, they put a dog leg in the beam to that side, which goes in to the bushing at a straight approach. (the leg by the logo)

I just bought my 2014 GMC Sierra All Terrain Edition. I was to use my stock 20" wheels and add 33"x12.50R20 toyo rt tires. What lift would you guys recommend and why? Trying to avoid any rubbing or clearance issues and looking to install level kit myself. Thanks

    • I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!
    • I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be. 
    • I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!
    • I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify. 
    • I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
